"Eighty thousand years ago, we had the opportunity to develop many Green Planets, as we'd sent out numerous communication devices. Unfortunately, a war broke out that bombed the Empire Technology Tower into ruins. I was left with only this single phone, which is how I'm lucky enough to be in contact with you. The other Green Planets remain unreachable because interstellar calls require a dedicated, one-to-one connection. Recently, Xuanwu Star has sent out many more phones, but it will take another eighty thousand years for them to reach those planets," Gao Si said.
"Can't your Cosmic Battleships or Spaceships reach the speed of light?" Zhang Bin asked.
